COMBINATION STOP-ACTION FOR ORGANS.

SPECIFICATION forming part of Letters Patent No. 456,768, dated July 28,1891.

Application filed February 4,1891. Serial No. 380,119. (No model.)

To all whom it may concern:

Be it known that I, LEONARD D. MORRIS, a citizen of theUnited States,residingat Springfield, in the county of I-Iampden and State ofMassachusetts, have invented new and useful Improvements in CombinationStop-Actions for Organs, of which the following is a specification.

This invention relates to improvements in combination stop mechanism oractions for organs,and more particularly pipe an d church organs,although the invention may be utilized in connection with reed-organaction.

As well known, in church-organs there is a series or several series ofstop-rods for controlling the pipe-registry on the proper working ofsuch rods for securing various musical effects-as, for instance, forteor piano or other well-known effects or modifications thereof.

The object of this invention is to provide a mechanism on or in relationto the stop or stop devices of any of the series thereof which may beadjusted or set before the playing, so that at any time desired duringthe playing of the instrument such of the stops as have their adjustabledevices adjusted may be as a combination readily and simultaneouslyoperated, and which mechanism shall be unusually simple and convenientof operation.

The invention consists in the construction and combination orarrangement of parts, substantially as will hereinafter more fullyappear and be set forth in the claims.

Referring to the accompanying drawings, it will be found that themechanism of this invention is clearly and fully illustrated both in itsapplication to the usual stop mechanism of a pipe-organ and also more indetail.

Figure l is a perspective view of the mechanism in its application tothe usual stop-action. Fig. 2 is a horizontal crosssection of one of theusual stop-rods of the action and a plan View of the novel devices orportions thereof Which act thereon. Fig. 3 is a side View of the partsshown in Fig. 2. Figs. 4c and 5 are side elevations taken at rightangles to the view Fig. 3, with certain of the parts shown as in changedpositions. Some of the portions of said latter figures are, however,shown as in vertical section taken on the intersecting plane indicatedby line a"- m,

Fig. 3. Fig. 0 is an enlarged perspective view of one of the adjustabledevices for a stoprod. the same being shown as at the side opposite tothat at which each of such blocks are shown in Fig. 1.

In the drawings, 1, 9, 3, and 4c represent stop-rods, here shown asvertically applied and movable and being a few only of many thereofwhich are comprised in the organ-action. The said rods are operated inthe usual manner through means of the horizontal knobbed draw-rods ll,12, 18, and 14:, the elbow-levers 5 5, the connecting-rods 6 (5, and thesecond set of elbow-levers 7 7. The stop rods 1 2 3 4:, &c., areconnected to respective slides 10 10 of the wind-chest through theangular lovers 0. In Fig. l the stop-slides are shown as closed and thestop-rods therefor in their upper positions, the knobbed draw-rods atsuch time being in their inner positions.

Each stop-rod l 2 3, &'c., is equipped with a rocker-block A, which isadapted to rock or tilt on a horizontal pivot 16. Each rockerblock isformed at one side with a pair of Wings (L and Z), extending laterallyto the plane in which the block is capable of moving, one of said wingsa being above the pivot 10, while the other thereof is below thepivot,and on its opposite side the said block is provided with another wing(1, also extended laterally to the plane of movement of therocker-block.

13 represents a slide-rod which ranges horizontally past the series ofstop-rods 1 2 3 4-, and opposite each of the latter said slide-rod isprovided with inwardly-extending lugs f and g, the one f of which is atabout the height of the upper block-wing (t when the stop-rod is in itshigher or normal position, while the other lug g is at a heightcorresponding to that occupied by the lower blockwing when the stop-rodis in its lower, work ing, or slide-opening position.

(J represents a slide-rod which ranges horizontally past the series ofstop-rods 1 2 3 +L, and opposite each of the latter said slide-rod isprovided with a lug h, which is at aboutthe height of the rocker-blockwing (I when the stop-rod and block are at their lowermost orstop-slide-opening positions.

At one side of the series of stop-rods is a horizontally-rangedrocker-bar D, which has a series of armsjj, respectively adjacent theICO rockerblocks A, and said arms serve, on being swung, when thestop-rods, or any of. them, are in their upper positions and the saidblocks, or any of them, are swung into one of the positions which theymay be made to assume, to contact with the tops of such rocker-blocksproperly positioned therefor and force them and the stop-rods down toopen the stop-slide. There is also at the front of the stop-rods anotherhorizontally-ranged rocker-bar E, which has a series of arms Z Zrespectively adjacent the rocker-blocks A, and said arms serve, onbeingswung upwardly as the said bar is rocked, when the stop-rods, or any ofthem, (with the blocks A,) are in their lower positions and said blocksare swung into one of the positions which they may be made to assume, tocontact with the bottoms of such properlypositioned blocks and raise thestoprods, re storing the stops to their normal positions. A singlepedal-lever F operates to rock both of said bars synchronously throughthe rod 7t, connecting said pedal-lever and one arm of theintermediately-fulcrumed lever 'i, and the connecting-rods e e betweenthe arms of said lever i and the rock-bar arms 01 and o, it of coursebeing seen that said barsD and E rock and the arms j and Z thereon swingin opposite directions.

The practical advantages of the mechanism described will be more clearlyunderstood upon an explanation of the operation or manner of use of thesame, and therefore it will be assumed that the organist beforecommencing to play prepares the mechanism so that at a desired timeduring the playing he may bring in a musical effect produced by aconcurrent opening of slides corresponding, for example, with stops 1,2, and 4, and yet previous or subsequent to such desired point of timehe may employ for a time either of the said stops 1, 2, and 4:, asordinarily. Therefore in preparing the mechanism as next above indicatedhe draws out drawrods 11, 12, and 14, thereby placing stop-rods 1, 2,and 4 and their blocks in their lower positions, and it is to be assumedat this time that all of the rocker-blocks are in their normalpositions, standing about vertically, as indicated in Fig. i. The wingsZ) of the rockenblocks 011 the said depressed stops are now in thehorizontal line of movement of the lugs g on the slide-shaft B, and 011pushing the latter inwardly the lugs g, contacting with wings b, therocker-blocks on stop-rods 1, 2, and at are tilted, so that the upperportions :11 of the blocks are in planes coincident with the courses ofmovement of the down-swingin g arms j on rock-bar D, although at thistime the tops of the blocks A are at or below the line correspondingwith the limit of downward movement of said armsj, and this position ofthe parts, comprising one stop-rod and the members coacting therewith,is shown in Fig. 5. The slide-rod B is then drawn out or restored to itsnormal position, carrying the lugs g free from the wings Z). Thestop-rods and a are restored to their normal and. slide-closingpositions by pushing in the knobbed rods 11, 12, and 11-, and now thesaid stop-rods have the tops of their rocker-blocks directly under armsjj of the bar D. The organist in the point of his play desiring to bringin the musical effect produced by opening slides connected to rods 1, 2,and 1, does so by swinging the rock-bar D through pedal F. As the rodsare thus depressed, the knobbed stops 11, 12, and 1% are forced out. Theorganist having in a speedy manner availed himself of the combinationdesired, may, to terminate the musical effect thereby produced, push inthe forced-out stop-knobs one after another, which merely raises thestop-rods without changing the rocker-blocks thereon, and the samecombination may be again brought into play by again depressing thepedal.

In order to destroy a set combination, the stop-rods 1, 2, and 1 beingin their normal positions, with their rocker-blocks obliquely tilted,this may be done by forcing in the slide-rod B, when the lugs f,thereon, engaging the upper wings a on the tilted blocks, will swing thelatter back into their vertical positions, when of course any downswinging of the armsj will affect nothing. Should there be, however, inthe combination a great number of stops, and, having been once used, norepetition thereof is desired, the stops of such combination may berestored to their slide-closing positions and the combination may bedestroyed in a somewhat different manner from that already indicated.Thus the slide-rod C is forced in and certain of the lugs 71 thereonengage the wings (I. on such of the rocker-blocks as are comprised inthe combination, and which wings d in the depressed positions of saidblocks are at the same height as said lugs 7L. The blocks being thusrestored to their vertical positions, are by their bottoms then capableof being ongaged by the arms ll of rock-bar E, which on being upwardlyswung by the depression of the pedal E raise the stop-rods, leaving therocker-blocks in their primary or normal positions.

lVith respect to more precise details, each rocker-block is secured onits carrying stoprod in this wise: A collar or apertnred block 20 isfitted over the stop-rod, and confined in place thereon by aset-screw,and said apertured block is provided with laterally-extended ear-pieces22, between which the tongue 23 nected by the pivot-pin 16.

The lugsf, g, and h are formed as extensions of apertured blocks orcollars, which are fitted and by set-screws secured on the sliderods Band C, said lugs being therefore readily adjusted for their properjuxtaposition relative to the rocker-blocks in the setting up of theaction.

The series of stop-rods in the organ usually of the rocker-block A isentered and on which the same is supported and conconsists of a score ormore of such rods, each of which is of considerable length, and it ispracticable to provide for each stop-rod two or three of therocker-blocks at different heights thereon, thereby forming two or threerows or series of such rocker-blocks similar to the row described and tocorrespondingly provide push-rods and also rocker-bars D E, as well asan actuating-pedal for the latter. Therefore a combination may be set,say, on and by an upper row of rocker-blocks and coacting devices,another on an intermediate set, and still another combination on a lowerset, each to be availed of at different times in the playing of theorgan. This is, however, only carrying out the invention in itspractical application in the organ in a manner which would be manifestto any one versed in organ construction and cognizant of the essentialsof this invention.
